22.3.4 EPS CPU Bay Interconnections
For the New Configuration:
• The FACU power supply and the CPU master motherboard are connected through the PDI board.
• Connect the power supply's "RUI+ Earth Detect" (P9 on the EPS card) to the Earth Fault (P1) on the RUI+ CPU Motherboard card.
• To connect the RUI+ CPU Motherboard to adjacent cards that do not communicate through the PDI (2" motherboards for example),
insert a male-male 10 pin header into the Motherboards's female ten pin header (J8) and insert the other end into the adjacent card.
22.3.5 EPS CPU Interconnections in Expansion Bays
Expansion bays comprise all bays other than the CPU bay. If you are installing a two- or three-bay FACU, you will be using expansion bays
(refer to Figure 30).
The power distribution interface (PDI) is mounted to the back of each expansion cabinet. The PDI contains slots for up to eight 4" X 5"
cards. Since the PDI carries power and data across the entire bay, it solves most interconnection issues, especially between 4" X 5" cards.
Refer to "Step 5: Installing Modules into Expansion Bays " for instructions on mounting 4" X 5" cards to the PDI. Also bear in mind the
following variations:
• In a remote expansion cabinet, a transponder interface card (TIC) requires additional interconnections. This occurs in MINIPLEX
systems. Refer to Installing 4100ES MINIPLEX
• Regular motherboards require non-PDI interconnections to each other and to the CPU. Refer to "Step 5: Installing Modules into
Expansion Bays."
22.3.6 EPS CPU Basic Bay-To-Bay Interconnections
Panels with two or three bays must be interconnected properly so that they function together as the central point of a standalone or
MINIPLEX system, or as a node on a network.
• The CPU bay can be connected to a local expansion bay by connecting the P2 or P3 connector on the left end of the CPU PDI card to
the expansion bay's PDI P1 connector.
• Figure 96 shows a typical interconnect using P2 on the CPU PDI to P1 of the first expansion bay.
• To connect two adjacent expansion bays, route the 734-008 Harness from P2 or P3 on the first PDI to P1 on the PDI in the next bay.
Jumpers P4 and P5 are set to positions 2 and 3 (right) to provide card power to the bay from a power supply (EPS, SPS, XPS, or RPS)
located in the same bay. Jumpers P4 and P5 are set to positions 1 and 2 (left) to provide card power to the bay from P1 on the PDI.
Note: Interconnections can become more involved if regular motherboards are used. Refer to "Installing Modules into Expansion Bays" if
this is the case.
Figure 96 shows the basic CPU interconnections in a 4100ES EPS FACU.
